Table 3 provides guidance for selecting appropriate values from Tables 2 and 4.

Table 3

Guidance on management and input for cropland and perennial crops

Management/InputGuidance
Full-tillageSubstantial soil disturbance with full inversion and/or frequent (within year) tillage operations. At planting time, little (e.g. < 30 %) of the surface is covered by residues.
Reduced tillagePrimary and/or secondary tillage but with reduced soil disturbance (usually shallow and without full soil inversion) and normally leaves surface with > 30 % coverage by residues at planting.
No tillDirect seeding without primary tillage, with only minimal soil disturbance in the seeding zone. Herbicides are typically used for weed control.
LowLow residue return occurs when there is due to removal of residues (via collection or burning), frequent bare-fallowing, production of crops yielding low residues (e.g. vegetables, tobacco, cotton), no mineral fertilisation or nitrogen-fixing crops.
MediumRepresentative for annual cropping with cereals where all crop residues are returned to the field. If residues are removed then supplemental organic matter (e.g. manure) is added. Also requires mineral fertilisation or nitrogen-fixing crop in rotation.
High with manureRepresents significantly higher carbon input over medium carbon input cropping systems due to an additional practice of regular addition of animal manure.
High without manureRepresents significantly greater crop residue inputs over medium carbon input cropping systems due to additional practices, such as production of high residue yielding crops, use of green manures, cover crops, improved vegetated fallows, irrigation, frequent use of perennial grasses in annual crop rotations, but without manure applied (see row above).
